Ok, opened bowl under carby, was polluted with a orange gel substance along with fuel. Even after cleaning bowl, it appeard to be rusted. Decided to remove carby to clean the entire unit as per a youtube video pointed out in another post by grumpy. Whilst was able to clean the main jet and emulsifier, also cleaned out needle & seat area. However, when going to reassemble, noted that the gaskets both inboard & outboard of the carby were not much chop either.
Decided to check up on some replacement gaskets & possibly carby. Found that cost was a little high, but local shop (Not a Sanli rep) did offer me a recent trade in for $20 (Branded as a Rockwell) which seemed to have all the parts.
I checked the donor when I got home & the carby & fuel system seemed nice and clean. As a result, I have now swapped over everything from the fuel tank to the inlet manifold. Tank, lines, fuel filter, carby and gaskets.
Tried to check for throttle workings. Found that the cable/actuator was broken. Donor machine to the rescue again, replacement actuator & cable now fitted.
Test fire of rebuilt machine still not successful. Have confirmed that there is spark. Had to give up for today due to meal commitments, but will try again tomorrow.
May have to remove air filter to see if it is clogged. Just because it appears to be clean, it may not be so. Donor machine only has a pure foam block for an air filter, so not game to use that.
Oh, and thanks for the replies and advice folks, I'm gonna need all the help I can get.
